Application tiled November I '0 all whom it may concern Be it known thatl. l lnwann Pl. lines, a citizen oi the United lltates, residing at Newllrleans, in the parish olf Urleans and State of Louisiana, haveinvented new and useful improvements in Ventilators, of which thefollowing is a specification.

My invention pertains to ventilators for cars, more especiallyrefrigerator cars; and it consists in a peculiarly constructed andpractically advantageous adjustable ventilator, designed moreparticularly :tor use on the body oi? the retrigeratmcar constitutingthe subject oil my contemporary application, filed. September 18, 1915,tlerial l lumber 51,4t25.

The present invention will be 'liully understood from the followingdescription and claim when the some are read in connection with thedrawings, acconuoanying and forming part of this s iecification, in.which:

Figure l is a side elevation showing my novel ventilator as properlyapplied and with the hood in its operative position.

ll ig. 2 is a longitudinal, vertical section of the same.

Fig. 3 is a top plan view illustrating the hood as thrown back touncover the opening that it normally controls.

tiiinilar numerals of reference designate corresponding parts in all ofthe views of the drawings.

The car body 1 is provided in its top wall with an opening; 2., borderedby an upstand ing flange 3, but otherwise the said body may be of anydesired construction and type Without attecting my present invention.

Hinged at 4: to the body 1 is the bass of the ventilator; the said basebeing oil? angular :Form in vertical section so as to con tain arectangular frame 6 which is provided at its underside with a gasket 7,designed to bear on the metallic lining 8 of the opening- 2 and therebyrender the closure air tight when. the ventilator is closed. lhe frame 6is secured in the frame in any approved man ner, and it serves, in turn,to hold the flange 9 ol the ventilator hood 10 against thehorizontallywlisposed portion of the base 5 with a view to stronglyconnecting the said. hood with the base.

ilny suitable means may be employed :lfor detachably fastening" theventilator in. its working position; the fastener 11 being shown by Wayott eirample as a type that is adapted to be used in combination with aspecification of letters Fatcnt.

i, padlock so as to prevent an unauthorized person entering the carthrough the open ing ili'; shown in l igs. 2 and 3, the hood 10 isprovided with a front wa l, the upper portion oit' which and the top oilthe hood descril .2 a part ol? a circle, as 'iuditaited by 19. In thesaid circular wall is formed an opening 13, which is controlled by guardl-il, oil: reticulated material, tired to the wall 12 and curred inconitoirlnity thereto. i-lt opposite sides of the opening andimmediately in trout oi? the pain rd it are guides 15 which describe apart of a circle, as clearly shown in l ig. 2. lllovable in the saidguides 15 is a curvilinear impcritoL'ate closure plate lll which whenclosed manifestly adapted to prevent the passage of air through theguarded opening it curvilinear perto- J. rated ha r 17 is lined to i thetrout ol the hood 10 above and below the opening 13, and on the troutoil? the lower portitui oi the closure plate 16 is lined a bifurcatedarm ltl, which receives and is movable Freely on the bar ll. The saidaria 153 is provided with tr- 'isversc apertures 19 designed to beregistered with the apertures of the bar it so as to receive a Fasteningpin 20 that is connected with the arm 18 through the medium olf a chain21. By virtue of this provision it is n'ut'uijliest the closure plate 16may be closed to a greater or less extent, according to the volume ofair it is desired to let into the car; also, that the said closure platemaybe ad justabl y lined in the DOSllllOl'l in which it is placed.

lln the hood is a handle 29;, through the medium ot which the hood may,when unfastoned, be swungbaclnvardly and down wardly into the positionshown in l 3 so as to leave the opening; 2 entirely uncovered. From thisit Follows that the opening 2 may be utilized for the eonvei'iientplacing of ice or any other substance desired in the car body.

lt will be gathered from the tlioregoingr that my novel ventilator iseasily adjusted and is highly e'tlicieut tor the purposes ascribed toit; also, that the ventilator is well adapted to withstand the roughusz'ige to which car appurtenances are ordinarily subjected.

ll-laving described my invention, What I claim and desire to secure byletters Pat out, is:

The combination of a body having an opening in its top wall and anupstanding:

llllli lllltl flange bordering said opening, and a ventiside a gasketopposed to the upper end of lator comprising a base and a hood havingsaid upstanding flange of the body.

an opening and means for controlling said In testimony whereof I havehereunto set opening; the said base being of angular form my hand inpresence of two subscribing wil- 5 in vertical section and hinged to thebody nesses.

in position to receive said upstanding flange,

and the hood having a flange disposed under B SH the horizontal portionof the base, and a Vitnesses: v frame secured in the base and opposed tothe R. G. EUs'rIs, l0 flange of the hood and having at its under M. E.KNIGHT.
